|
|
Has anyone here done CB shorty IDF manifolds on Revmaster 049 heads? My DRD heads based on the 049 RM castings with 12mm plugs has virtually no space for plug leads and accessing the studs to bolt the manifolds down. My engine builder thinks I'll hate it. Reckons it's near impossible to fit the leads. Will surely also require full removal of the carbs and inlet manifolds to get at the spark plugs. I haven't been able to check it out yet but it has me concerned.
Can anyone here shed some light on the issue?

I used a wobly and shortish spark plug socket, to break them loose, then i jam a piece of fuel line on the end and twist it out , the reverse for install. it can be done with the carbs in place... not fun, requires a certain level of patience but it can be done _________________ Schnell, SCHNELL!

If you have any questions about Forged ICON 4032 VW pistons just shoot me a line. |

also gotta cut the intake studs short as possible and use the tiny nuts with the flange, they really help https://www.thesamba.com/vw/classifieds/detail.php?id=929112

Yeah I'm starting to figure that out. I guess it's the price you pay for a rear trunk. _________________ Sydney, Australia.

Thanks for the tips. Exactly what I need. Did you have to do any mods to the cooling tins behind the manifold? _________________ Sydney, Australia.

It's been a while but yes I remember some dimpling and trimming of the dual port tin piece that looks like a mustache? _________________ Stop dead photo links! Post your photos to The Samba Gallery! |

aircraft nuts with the wobble and a 10" extension, and pull the carbs/manifold when you want to change the plugs
keep a supply of manifold gaskets, and it's a fun job getting the plug wires on/off
