Guest Tom Dimma Posted February 23, 2007 Ive just put another TU3S engine in my car as the tensioner went in the old one. the engine is in and all wired and plumbed in, but when i got to start it it turns over but wont start im getting a spark to each plug and im getting a 2ft flame out of the carb as well as alot of back firing im just wondering if anyone knows what could be causing it could it be a sticking valve??? it is all timed up using the marks and the firing sequence is correct. any ideas???

Ryan 99 Posted February 23, 2007 Have you triple checked the firing sequence? Are you sure you aren't thinking the cylinders are numbered starting at the opposite end? Share this post Link to post Share on other sites
Guest Tom Dimma Posted February 23, 2007 which end does the firing sequence start? Share this post Link to post Share on other sites
Ryan 99 Posted February 23, 2007 Right to left - number 1 is at the gearbox end. Share this post Link to post Share on other sites
Guest Tom Dimma Posted February 24, 2007 Cheers that may explain why i have had flames out of the inlet manifold lol they were impressive tho lol Share this post Link to post Share on other sites
Ryan 99 Posted February 24, 2007 I've done the same a few times, but always realised before trying to start it. Don't ask why Peugeot decided to be arkward and start numbering things the wrong way round... Share this post Link to post Share on other sites
