Saito Fg33r3 modification.
Hi guys, firstly let me apologise if there is another thread I couldn’t see it, l got my Saito Fg33r3 and it wouldn’t run properly on number 2 cly. Not matter what the mixture etc I tried if I flew it and throttled back I would loose number 2. It could of been due to the very oily plugs or timing issues. I fitted the MMM back plate today and had a test run in the garden with the blank plug over the crank case vent and running on 30-1 oil. Wow what a change the “fluffy” mid range has gone and it’s now far far quicker in response, plus I let it idle for a min and it reved up straight away, before the lower plugs would get oiled up and it would struggle before clearing itself.
i haven’t got the new timing ring on yet but I have measured the timing of the standard ring and I have
number 1 - 35 degrees
number 2 - 40
number 3 - 34
these were not as bad as I thought they could of been but still not the 28-30 degrees they will be soon. I look forward to seeing what it is like after I have fitted that. Im getting 7250rpm on the ground with a 17x10 prop. After the timing ring I think I will go up to a 17x12
has anyone else measured the timing on their standard Saito radials?
