modified camshaft

#1 Post by ken » Wed Sep 12, 2007 8:58 pm

Hello from a non mechanic landrover owner. i recently rebuilt my 2.25l series engine (under supervision) and put in a camshaft with greater lift (187 deg intake, 188 deg exhaust, .302 "int., .304"exh lift) than the stock camshaft. The solex carb isn't up to the extra requirement. I have increased the venturi to 36, put in a 160 main jet, and a 240 correction jet and it runs okay with these changes, provided there is no air cleaner at all. when throttle is increased rapidly, gas sprays out the top of the carb, (but at least the power is okay, as long as there is no air restriction).
I am contemplating either
1. pulling the cam and putting in a milder (closer to stock) cam (big job) or
2. switching to a dual weber carb setup and larger exhaust ($$).
Does anyone have experience with the second option? I would appreciate any advice, thanks, Ken.

I ran a dual weber progressive for years on my 2.25. It was economical (as much as any 2.25 can be) at low revs but provided a good boost of fuel if you put your foot into it and opened the second barrel.

I just used an adapter to adapt it to the standard manifold, but purchased along the way a carb and manifold from a 2.5 litre military late Series III or Defender. Anyway, that may be available if you're interested, as I loaned it to a friend to try out and I don't think he's done anything with it. It cost me just over $200 for the carb and manifold, and the carb could use a kit, but if you're interested, send me a PM.

Dave
