How do guys.....I'm in need of pointers or ideas please.
My standard T5, only jetted to suit Sip exhaust, si24/24g carb has started to over fuel and builds up in crankcase. Changed needle and float but still the same. When I turn engine by hand, you can see the fuel getting dumped onto the slide and both main jet stack and idle jet has fuel bubbling out the tops.
Is the fuel level in the float bowl TOO high?? Or could there be another reason??
Any help or ideas much appreciated......just doing my head in now 😡😡😡.

Also, for your T5, post in the Not So Modern section. A few T5 owners will be able to give better advice.
