morning the guys,

i have been having a problem with cylinder two in my pinto running R1 carbs. there is lots of back firing and the carb for the cylinder seems as if its choking as its spluttering all the time. all other cylinders and fine, no choking noises or puffs coming from them, any idea what it could be?

Cheers Alex

Have the carbs been set up [ balanced ]
have you had them running ok or have you just put them on

Morning Alex, your up early.
If you have checked the spark is good on that cylinder.
You need to see if there is any crap in the jets on that carb. The mixture screw is correct because it was checked. Also check the float level. Did you check the valve clearances.
