I agree, I like my dead-center tool.. I use it with every mounting. I get the engine in the position I want, then I use a few simple clamps to hold it on the mount, while I make my marks with the dead-center tool. Your local hobby shop, or even hardware store should have a tap/drill set... I'm thinking its a 6/32 size needed for that size engine.. double check me on it.. If your kit came with bolts.. theres a good chance they're metric of some sort... I probably wouldn't use them.. I'd get some Dubro machine/allen bolts... and the Dubro tap/drill set... Plastic mounts actually tap out very nicely if done carefully.... DO NOT try to squeeze a bolt into them though...inotherwords... use the drill bit included with the tap, cut the threads. Don't try to cut threads using a bolt... that will split the plastic... Of course you can drill the holes oversize and use lock-washers/nuts.... that works also.. and is a way to save a mount if your threads don't work out. Good luck.
