Help

#1
Hey looking for some help I have a 3HP Briggs and Stratton 1969 Engine made with no Tapets or Cam Shaft and wondering if anyone has ever worked on a similar engine could help me out! Trying to free up the valves (Intake and exhaust) as they are stuck shut. The Fly wheel moves But stops at a Point someone Said the stuck valves were in the way just looking for the easiest safest and fastest way to break them free. Photos of Valve springs and intake and exhaust port thanks

For your sitaution WD40 is CRAP compared to Gibbs. If that does not do it try soaking the entire top end in Evaporust (Google it) to free it up

You know there are many different WD-40 products these days, right? The original WD-40 was developed to displace water/moisture (WD: Water Displacement, 40: 40th formula), which it does well.

Here is their Rust Release Penetrant. I use it. Don't knock it if you haven't tried it.
