EZ-GO ST350 (2004) engine and wheels..

[mjf1604]

Hi Everyone!
following much help from people on here I have rebuilt the MCI engine in my 2004 ST350, and it now runs smoke free and with plenty of power!

The one thing, there is a slight rattle at low revs, sounds like a bit of metal 'tinking' on another, can anyone think of anything obvious that can cause this? maybe something I have put back on wrong??
I have tried turning the engine by hand and cant hear it, (and spun the starter motor over with no belt, and thats perfectly quiet). maybe its the drive clutch?

2 other questions I have:

Does anyone know what is the biggest tire size I can fit with the standard factory lift the ST350 has? As stock they come with 22's but would 23's or even 24's fit? Would be cool to get it riding a bit higher, especially while I need a new set anyway

and secondly, on the MCI engine does anyone know how to remove the spark plug wires? I have an older workhorse with a pre-mci engine and they just unscrew from the ignition coil, but they don't seem to want to unscrew on the newer MCI coil, any ideas?

I'm keen to get them changed as I replaced the ones on the older vehicle and there was a big improvement in spark and the power delivery was vastly improved, and as the parts came in the tune up kit it makes sense to fit them.

cheers
