I want to know what size glow plug do I use in a Moki 1.35?
I even went to their web site and cant find it.
It is glow fuel, is it a glow plug or a spark plug?
Thx for all the help

You live in Orlando...call or go to Graves they'll know and have it in stock

A standard medium glow plug will work fine.

You can use other glow plugs to adjust for problems... e.g. a long plug for an inverted engine, etc.

I called Graves Hobbies, the guy said "you can probably get away with an OS 3"
That is why I dont like that particular Hobby Shop.
I have nothing but bad experiences there.
I dont want to get away with a #3, I want my engine to run well.

The man in the hobby shop is right. You have to try different plugs to see which one works for your engine. As opjose says you can try other plugs to see if they work any better, but you have to start somewhere. Unless you are going to try racing or some high performance activity the OS3 will probably work.

i like OS F plugs in all my 1.20 on up glow 2/4 strokers.... i get a really nice lower reliable idle too

Lop, did you know there is a glow engine forum with a lot more advice from people that are really using that engine? Well worth the trip to go there and look. There is a lot of info about the Moki, little things like using FAI fuel and different heat ranges of glow plugs. Moki has a few more likes and dislikes then other two stroke engines most people are used to seeing. It's an engine most people don't see much of at there fields. Great engines but they do have a few quirks of there own. Go take the trip to the glow engine forum instead of beating your head against the wall here.

OS F or another good four stroke plug. FAI fuel (no nitro) or 5% max nitro fuel. Moki's take quite a while to break in.

Yeah, many .60 and above 2 strokers come with "long" plugs from the manufacturer, so I've taken to use them in .60 sized engines and up, even in a few inverted .46's too.

Here are some stock plugs for comparison.
