Mega-DITTOS to SOME of what HermO said .....

'cept that Eddy carb ...

That is a stone-age carb compared to the TQ. You want FUEL ECON ? .... stick with the TQ.

Get an older FACTORY service manual .... good info and tips in there. PLUS ....go to Napa and get a set of brass floats. Those plastic floats(using the alky-blended fuels) ...are NOT the plan.
