Finally got a bus

My bus has a 2110 SP with stock cam, carb, etc and it is a lovely engine, very torquey. It was with the bus when purchased, was built by James Arredondo. Idles and drives around town like a stocker, but pulls like a train from low RPM.

awesome bus guy, if i have to get a new case then i'll do the 2110.
i got my exhaust from kymco today, much heavier than the bugpack header thats the same size.
looks great even got he flanged jtubes to replace my heater boxes.
so what do y'all think is causing my loss of power around 4k rpm while floored in 3rd?
not enough air in the engine compartment, floating valves, running lean, spark jumping in the distributor cap, etc........
i just have to hook up my mallory CDI box soon and my CHT gauge.

here's some pics finally of the rust repaired, new kymco exhaust, engine bay psi gauge, and weird stuff on friend's engine.
now if any of you could tell me where to put my mallory cdi box, engine bay or interior, that would be helpful too.

if you need some metal work done i can give you the guys number. he's the other guy in the last set of photos. he did good work.
it would've been better if i was planning on making the bus show worthy.

so i'm still loosing power around 4k especially when i have it floored.
it doesnt loose power immediately, but after i've been at 4k for a minute or so then it starts to bog down and loose power. or when i'm i n3rd it'll loose power at almost 4500rpms. i let off the gas for a second and let the rpms drop then its good again.
i went to 150 jets from 145, the 60 for the other jet hasnt changed. ICT carbs.
single port with some work done to increase flow and stock valves,
100 cam with 1.25 ratio rockers,
1 3/8ths exhaust with jtubes and single quietpac,
SVDA distributor with petronix,
.28 gap on plugs, 8.5 performance wires, bosch blue coil,
everything balanced.
this problem developed after i tightened up my accelorator cable, i wasnt going wide open throttle before.
my plugs are a light tan color.
205/60/14 tires with 4.12 stock trans, straight axle.
at 4000rpms i'm doing about 70mph.

my next step if to install my air/fuel ratio wideband gauge and see what it says.
also i have a mallory CDI box i havnt installed yet.

please let me know what my problems could be. need some help.

Yes... put the wideband on....NOW. lol. I wouldnt drive without it.

sounds like your running out of fuel. What fuel pump? What psi? new fuel filter/s? tank restored no restrictions/blockage on tank outlet?

stock fuel pump, 2.5-3 psi.
tank was cleaned up when i had it out a coupel years ago.

kingodirtp3 · Posted: Mon Apr 04, 2011 5:11 pm Post subject:

could my problem be the stock fuel pump? i have 2.5-3psi all the way to 5k

mightymouse · Posted: Mon Apr 04, 2011 5:48 pm Post subject:

Well, by running out of fuel i mean you could also have too small of jets, or float levels set wrong.
The wideband will tell you.
If it goes lean off the scale you will know right away.
When you said your throttle cable adjust started this issue, that sounds like a fuel volume issue.
You couldnt add enough air before for the amount of fuel you had. Now you can by opening the throttle plates further than before.
So rather its that the jets are too small, or your pump isnt providing enough volume you will see it on the WB gauge.
Then its just a matter of diagnosing which one is the cause.
follow me now? Smile

thanks! i'll get the wideband hooked up tomorrow

kingodirtp3 · Posted: Tue Apr 05, 2011 10:09 pm Post subject:

so i installed my cht gauge, hooked the wires up backwards. yea i didnt read the directions.
i had to extend the wires about 3 ft using normal wire.
and it doesnt work....
i did some searchign and found out the wires are special k somethign thermo wires.
so i have to go to an electronics store to get soem wire to make it work.

thats another idea, thanks! once i get real low on gas i'll do that

kingodirtp3 · Posted: Tue Apr 12, 2011 1:30 pm Post subject:

we're almost done with my friends suspension. he got the adjustable beam DIY kit from bus boys.
so if anyone around monterey, or salinas knows how to do it let me know. he may need your help.

kingodirtp3 · Posted: Sat Apr 16, 2011 6:55 pm Post subject:

so i hooked up the a/f gauge, at idle i'm at 11.5 to 12 once i get up to 3000 rpm it goes up to 13.8 to 14.4. it gets 14.5 to 14.8 at 5000rpm.
so it seams i'm rich at idle but good after that.

65BAJA · Posted: Sun Apr 17, 2011 10:57 am Post subject:

Does it stay the same as you are losing power or does it go up more? Looks like you could fatten up the mains and lean out the idles. Have you had a chance to check the screen in the tank?

it didnt come with enough harness to reach to the dash so i couldnt drive it, i just reved it in the driveway
it also wont stumble when cold, but once the engine warms up i cant get to 4000rpm most of the time.

so i've been informed that i need to actually drive my bus wit hthe air fuel gauge connected,
doing it in the driveway doesnt mean anything.
i can set up the idle though, right now i'm too rich so i'll turn the mixture screws to fix that.
i ordered a replacement harness for my gauge so i could extend the harness to run up to the dash and taek it for a drive.
i also was told the 150 jets i put in was too much.
i did return my idle to 38 instead of 42 with the hose connected. it seamed to drive little better and it didnt bog down as much at 4000rpm once warmed up.
i'll go get the O2 bung welded in today i hope. i dont like using the adapter i got, i'll save that for other vws.

oh and if anyone has the instructions for installing the mallory cdi from aircooled.net can you please email me a copy?
aircooled wont send them to me since i didnt by the box from them. i got a great deal so i had to get it somewhere else.
