2007 MTD Tiller with a 5hp Honda engine

Hi.....I am assuming that you have a bowl type carberator on that tiller. If so, the bolt on the bottom of the bowl, is the main jet. If you remove it, you SHOULD, see a hole drilled from the top down to a hole cross drilled thru, near the bottom. Run a small wire thru these to be sure they are clean. Other then this, I'd install a new needle and seat. You can purchase just a needle and seat set, no need for a complete rebuile kit. You will also need a bowl gasket, and if you have a primer bulb, you will also need a new intake gasket or the primer will not work worth a darn. Hope this is of some help, good luck

well
heres your 4 strokes

1 intake down
2 compress up
3 power stroke down
4 exhaust up


if you start with you start with the piston just a couple of degrees past TDC (top dead center) so that it has started its return down

now set the valves so they are closed:
if you have an adjustable valve clearance's then your clearances should be noticeable like 10 thousands ( you should be able to move the lifter ( rocker arm ) and it will be loose up and down

with the spark plug still out; so you can see the piston coming to TDC and passing it to come down

turn the flywheel and watch the strokes and the condition of the valves

1 just past tdc, the intake valve opens and the piston goes down for the intake stroke

2. jst as the piston comes around BDC the intake valve should close and return to tdc with all valves closed ( the compression stroke )

3 just past TDC the ignition will fire and the piston will return down with both valves closed( the power stroke)

4 just past BDC the exhaust valve opend , the piston travels up and completes the exgaust stroke.


and after completing the exhause stroke and arriving at tdc the intake valve opens and you start over again 1,2,3,4
