 |
|
Hello there. I have just installed a VW factory built (mexi) 1600 into my 71 bus. I put empi 34 dual carbs on it and was trying to sync them tonight. I noticed that the 3&4 cylinder side is running hotter/ warming up much quicker than the 1&2 side. I know this is fairly normal. My concern is that the carburator on the 1&2 side does very little when I adjust it liberally where as the 3&4 side carb is fairly touchy. It seems to be the case with the idle adjustment as well as idle air setting. The carb on 1&2 side seems to be sucking less air and that side is running cooler than the other 3&4 side. I got the carbs to read the same on the flow meter. When I rev it up it still pops pretty loudly.
I am thinking about adjusting my valves again tomorrow. I adjusted them on the bench and they were perfect (if a little bit tight)... I am hearing a bit more rocker arm "Ticky Ticky" on the 3/4 side, but that has been normal in my experience so far.
Can anyone give me some advice on evening things out?

Update:.........You ever mix the plug wires up? Heh...Heh... Amatuer hour over here. Luckily I didn't run it for very long sensing that something was off and will go back and adjust the valves before a second go at it.

Doesn't the Mexican engine have hydraulic lifters?
Never worked on one but assume the lash setting is much different.

I may be wrong, but I think that the Fuel Injected ones have hydraulic lifters. This is most definitely the standard rocker style.

 Rocker arms have zilch to do with hydraulic lifters which are on the inside of the engine.
Stock factory or 1:25 or 1:45 can be used when properly installed for Geometry.
Try adjusting the valves at "0" clearance (for hydros) and see how the engine responds. (thats what I have on my 1776cc Turbo)
OR the avg 0.006 with what the majority have. (NON Hydraulics) to see how the engine responds.
Hydraulics will clatter for 1-2 secs untill they fill with oil then will be QUIET. |
