[QUOTE="e21manic, post: 310403, member: 4288"] heyya guys, was doing some reading up on this carbie and on some forums they had not many good things to say about the 4A1. some even labeled it a lemon! :S vacum leaks are common and it warps easily. how true is this? how do i check the carb for warping? hope all is well with it!! reading up also on the other problems it has.... hmmm better come up with plan B in case i run into major issues! what other carb set ups would be ok for the M20. am not looking for a powerful set up but a decent one that balances fuel economy and power as well.. -some go the weber route but its a bit tooo $$$ for me in terms of FC and getting it in the first place i feel.. but then again, any thoughts on the webers? - was always fascinated by SU carbs. would a twin SU set up work well with a M20 engine? anyone seen this done before? possible issues? -any other suggestions? dont think i want to consider injection set ups coz.. i have this thing where i like to tinker around with my engine.. cant tinker muc with and injection can i? :p thanks for the advice guys!!!!
