Our adjustable timing kit used along with the Raceseng Rev Wheel is a game changer that allows you to dynamically set your ignition timing precisely to your desired setting. take a look at the instructional video we just finished producing which details setting your ignition timing with the...

:shrug:I was putting my engine back togeather and took a measurment of the keyway. The engine was from NR Racing. The key is filed down .060. From what ive read .006 will give you 1 degree so if that is true my is 10 degrees advanced I'm thinking thats too much? Its a mild build. It starts...

I want to build a simple light set up for drag racing events. starting lights I can handle but making a win/lose lane lights are kicking my butt. Any ideas? not spending 4k on a system,thinking about using laser lights or something like that from a garage door opener system. I would also...

I was given a few flatheads, I am assuming they are 5hp motors and one of them I noticed is a new build. It has a new .020 piston, aluminum rod, not pretty like arc's, more industrial looking, also steel sleeve, it has been decked to eyeballing zero deck height, has a new exhaust seat and cut...

I was wondering how to set the valve timing on a gc160. I was taking one apart for the heck of it last night and I didn't see any marks on anything. Anybody know what the deal is?

Hey all, I got a clone with 9.4:1 compression ratio, mild cam, 22 mikuni on gas, I was curious what timing some of you out there are using. I was thinking in 30 degree range, has 28 with straight key on arc flywheel, 34 with 6 degree advance keyway, I am gonna lap the wheel and run no key. thanks

I have a stock 5hp Briggs or some what stock shaved head ported and polished shaved the eye brows billet rod stock carb and strait piped would Advancing cam timing a tooth or two help performance or hurt or maby retarding the timing any input guys

hi guys, i was wondering if you have any idea how the old cars had adjustable timing, if i could build one for my bike?

lapping is over my head right now so is filing so I decided to get a 4* key. was hard to get out but managed. how do you put the new one in? its really tight, just tap it in or what?

Im new to the entire mini bike engine mods and was wondering how to do the timing in my 6.5 clone, and the use of timing keys. What exactly are they? what are the benefits of the 4* offset and 8*. what do the degrees mean? thanks

I tried to fire up the engine in the rupp roadster that I just got..The carb is fubar so I just put a few drops of gas down the spark plug hole to see if she would run..It was very hard to pull over..In fact it seemed like when it would fire it would almost lock up the engine and I would...

What is the real world difference between using the 4 degree and the 8 degree advance keys. I realize 8 degrees is more advance. Does the 8 degree tend to cause detonation on pump gas, or make it hard to start with the pull start? How about with the flat top and 5.5 cylinder head? I really...

I have a genuine honda gx200 and have the Long billet rod 3.313 (.10inch longer) and was wandering if i still use the 8 degree advance? Or would this be less due to the size of the rod? On one of the engine i will be using a honda aluminium flywheel so i take it that would need a 4 degree...

I am trying to figure where, or at what point on the flywheel when it passes the coil does it trigger the voltage to the spark plug? I am trig to change the timing by using offset flywheel keys, I had to make the keys because as usual they are not available for my engine. The coil has three legs...

new to the clone ohv type deal, building a mini drag and gonna do the motor too. besides a off set flywheel key, and "hoping" its advanced to whatever the key is, how do you check the timing? Degree wheel, timing lite? thanks..... mark

I have a 3hp briggs IC engine with a bearing on the crankshaft. How do I set the cam timing without taking that bearing off ? there is a punch mark on the crank counter weight . The bearing is pressed on the crank and I don't want to risk breaking it trying to get it off. Also what does that...

which way does the key go? Does the offset go towards the head or the back of the block? :confused:
